Could a similar scenario also happen when upgrading live apps from the app store, given that they are running a packet tunnel?
That’s certainly possible. The TestFlight and App Store upgrade processes are very similar, so it wouldn’t surprise me if the App Store upgrade process had a similar issue.
And, we’ve definitely had problems like this in previous iOS releasing.
Having said that, I’ve not seen other folks reporting this, and when this has happened in the past I heard a lot of complaints.
It sounds like you can reproduce the problem at will, in which case you should definitely file a bug. Make sure to:
Note down the times of each relevant event (that is, when you initially triggered the update, when you noticed it has stalled, when you disconnected VPN, and when the update completed)
Include a sysdiagnose log (per our Bug Reporting > Profiles and Logs page)
Please post your bug number, just for the record.
Share and Enjoy
